I specialize in White Hat SEO. Meaning I do not employ any spammy technique that might get a website penalized or blacklisted on any Search Engine. However there is 3 type of seo White hat seo, black hat seo and grey hat seo. But I only work on white hat seo. Because I respect my client and does not want their website will harm by black hat seo or grey hat seo. So I am only work on white hat seo.
